|---|---|
| Experimental: Giredestrant plus Everolimus |
Drug: Giredestrant
Participants will receive treatment with giredestrant 30 milligrams (mg) orally once a day (QD) on Days 1-28 of each 28-day cycle until unacceptable toxicity or disease progression as determined by the investigator according to Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST v1.1).
Other Names:
Drug: Everolimus Participants will receive treatment with everolimus 10 mg orally QD during each 28-day cycle until unacceptable toxicity or disease progression as determined by the investigator according to RECIST v1.1. Drug: LHRH Agonist Only premenopausal/perimenopausal female participants and male participants will receive a luteinizing hormone-releasing hormone (LHRH) agonist on Day 1 of each 28-day treatment cycle. The investigator will determine and supply the appropriate LHRH agonist locally approved for use in breast cancer. Drug: Dexamethasone Mouth Rinse A compounded alcohol-free mouthwash of dexamethasone (0.5 mg in 5 mL) will be supplied, where feasible.
